We have a red oak in the front yard and the tree leaves started disappearing since early spring. Initially it started at the very top and now spreading towards the bottom. Seems like some kind of bug/pest infestation maybe?
What are these and how to fix this problem? There are tiny holes on the leaves and brown spots on the stem behind.

I read some articles about these larvae/caterpillars that create holes and eventually eat the leaves.

Found these as well.
Are these oak leaf galls?
